The result (.375) is the distance the cutter starts from the I.D. of the part.

After the initial positioning, the next step of the program is to turn on cutter compensation and move to the I.D. of the circle.

The next step is to program a complete circle (G02 or G03) with a Z-Axis command of the amount of one full pitch of the thread (this is called Helical Interpolation).

The last step is to move away from the I.D. of the circle and turn off cutter compensation.

You cannot turn cutter compensation off or on during an arc movement. You must program a linear move, either in the X or Y Axis, to move the tool to and from the diameter to cut. This move will be the maximum compensation amount that you can adjust.
